A NOVEL EVALUATION METHODOLOGY FOR DETERMINING I-LEVEL TEST CYCLE-TIME IN MISSILE MAINTENANCE

The periodic testing cycle of missiles is a critical factor influencing operational readiness, reliability, and associated logistics costs, including maintenance, transportation, and testing. Despite the importance of optimizing these cycles, a clear understanding of the optimal testing intervals for different missile types remains underexplored. This study investigates the impact of various I-Level periodic testing cycles for K-type missiles, utilizing the "Important Factor Weighted Exponential Distribution Function (IFWEDF)" method to estimate and compare reliability across different intervals. A cost-benefit analysis is then conducted to evaluate the implications of extending the testing cycle. The results indicate that a three-year testing cycle optimizes reliability while minimizing costs. This paper offers a novel approach to missile maintenance strategy formulation and contributes to the existing literature by providing evidence-based recommendations for determining optimal testing cycles in missile systems. The findings of this research can inform future strategies for military maintenance planning and contribute to cost-effective operational readiness management.
